Is there a way or utility that will tell me if my machine is connected to an 802.11b/g/n 2.4ghz network or an 802.11a/n 5.0ghz network? Thanks, Paul

Your wireless card properties should provide that information, also the wireless router product lit or device summary should describe the Ghz at what you operate at. Control Panel\Network and Internet\Network Connections Select your Wireless card, right click "properties" Click on configure, right underneath "Connect using" "Your Network Adapter"\ Select the "Advanced Tab", look through the property settings, depending on the manufacture of your wireless it may provide a value for you. :P Advice offered, If you need more help it is advised to seek the council and advice of paid professionals. The answer is always 42, or reboot.
